I am trying to add a conditional yaml config file in a properties file but it's not able to read the env variable
hibernate.cache.redisson.config=redisson-${REDIS_MODE}.yaml
it is giving error
Suppressed: java.io.FileNotFoundException: redisson-.yaml (No such file or directory)
How can we resolve this?
It seems like the ${REDIS_MODE} env variable is not set correctly. Check the error message - the suffix from the env var is not present in the error message's file name. Ensure that env var is properly set and matching your configuration file and then retry.
Will be great if you can give the files structure. But base on the existing information, you can or programmatically set the Hibernate property, like:
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.env.Environment;
@Configuration
public class RedissonConfiguration {
@Value("${REDIS_MODE}")
private String redisMode;
@Autowired
private Environment env;
@Bean
public RedissonClient redissonClient() throws IOException {
String configFile = "redisson-" + redisMode + ".yaml";
Config config = Config.fromYAML(new File(configFile));
// Set hibernate properties programmatically
Properties hibernateProperties = new Properties();
hibernateProperties.setProperty("hibernate.cache.redisson.config", configFile);
applyHibernateProperties(hibernateProperties);
return Redisson.create(config);
}
private void applyHibernateProperties(Properties hibernateProperties) {
// Apply these properties to your Hibernate configuration
}
}
Or add property source annotation in your conf class:
@Configuration
@PropertySource("classpath:hibernate.properties")
public class HibernateConfig {
@Autowired
private Environment env;
@Bean
public LocalSessionFactoryBean sessionFactory() {
LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();
// Now you can resolve ${REDIS_MODE}
String redisConfigFile = env.getProperty("hibernate.cache.redisson.config");
sessionFactory.setHibernateProperties(hibernateProperties());
return sessionFactory;
}
private Properties hibernateProperties() {
Properties properties = new Properties();
// This will now resolve the placeholder
properties.setProperty("hibernate.cache.redisson.config", env.getProperty("hibernate.cache.redisson.config"));
return properties;
}
}
